Let's divide 25399270 by 578
We want to figure out the number of times 25399270 can be divided by 578.

Step 1:
The number 578 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 578

Going ahead to step 2:
If we divide 25 by 578, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 578

Let's proceed to step 3:
The number 578 fits into 253 0 times, leaving a remainder of 253.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 253, we end up with 253.
Fetch the next digit (9) from the dividend, attach it to 253 and continue: 2539 / 578

Moving on to step 4:
578 can be fit into 2539 4 times, resulting in a remainder of 227.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2312 from 2539, we get 227.
Grab the next digit (9) from the dividend, add it to 227, then carry on: 2279 / 578

On to step 5:
If we divide 2279 by 578, we get 3 and a remainder of 545.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 1734 from 2279 leaves us with 545.
Fetch the next digit (2) from the dividend, attach it to 545 and continue: 5452 / 578

Step 6:
578 goes into 5452 9 times with a remainder of 250.
Write down 9 as next digit of the result. 
Result so far: 439.0
The remainder is 250 after subtracting 5202 from 5452.
Grab the next digit (7) from the dividend, add it to 250, then carry on: 2507 / 578

Advancing to step 7:
If we divide 2507 by 578, we get 4 and a remainder of 195.
Record the quotient 4 as the next digit in the result. 
Result so far: 4394.0
The remainder is 195 after subtracting 2312 from 2507.
Bring next digit (0) of the dividend behind the 195 and repeat the process: 1950 / 578

Advancing to step 8:
If we divide 1950 by 578, we get 3 and a remainder of 216.
Put 3 as the next digit of the answer. 
Result so far: 43943.0
Subtracting 1734 from 1950 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 9:
The number 578 fits into 2160 3 times, leaving a remainder of 426.
The number 3 becomes the next digit in our result. 
Result so far: 43943.3
If we subtract 1734 from 2160, we get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 10:
If we divide 4260 by 578, we get 7 and a remainder of 214.
Write down 7 as next digit of the result. 
Result so far: 43943.37
If we subtract 4046 from 4260, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 11:
The number 578 fits into 2140 3 times, leaving a remainder of 406.
The number 3 becomes the next digit in our result. 
Result so far: 43943.373
Subtracting 1734 from 2140 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 12:
When dividing 4060 by 578, we get 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 43943.3737
Deduct 4046 from 4060 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
578 can be fit into 140 0 times, resulting in a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 43943.3737
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 14:
When dividing 1400 by 578, we get 2 with a remainder of 244.
Record the quotient 2 as the next digit in the result. 
Result so far: 43943.373702
If we subtract 1156 from 1400, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 15:
When dividing 2440 by 578, we get 4 with a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 43943.3737024
If we subtract 2312 from 2440, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 16:
1280 divided by 578 is 2 with a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 43943.37370242
The remainder is 124 after subtracting 1156 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The quotient of the division is 43943.37370242, and the remainder is 1.24e-07.
